The peeling means is formed so as to be opposed to the hole forming region, and in the hole forming region, a hot-water drip hole incision is formed so as to pass through the inner cover and the adhesive resin layer. A hot-water drip hole forming incision line is formed inside the hot-water drip hole forming grip so as to pass through the inner cover and adhesive resin layer.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of pouring hot water into noodles and leaving them to stand for a certain period of time, such as fried noodles in a cup.
The present invention relates to a lid member having a drain hole used for a container for draining.

[0002]

2. Description of the Related Art Conventionally, in a cup of fried noodles, the fried noodles are stored in a container made of expanded polystyrene or the like, covered with a plastic molded lid having a notch formed as a hot water hole, and the whole is shrink-wrapped with a shrink film. The fried noodles are stored in a packaged form or a container made of expanded polystyrene, etc., and a lid made of a laminate of paper and aluminum foil, which can form a hot water hole by piercing with chopsticks, is thermally bonded to the container. And the like, and a package form in which the whole is shrink-wrapped with a shrink film is known. However, when the former packaging type container is used, since the plastic molding lid is formed with a notch serving as a hot water hole, it has no gas barrier property and is not completely sealed. There is a drawback that the smell of the contents leaks outside. In addition, when the latter packaging type container is used, it is necessary to pierce a predetermined portion of the lid material with chopsticks or the like when pouring the hot water, and it is necessary to make a hole. There are drawbacks such as a risk of burns when piercing the lid from above the container.

[0003] As a cover material in which the above-mentioned disadvantages are improved, Japanese Patent Laid-Open Publication No.
000-109141,
Having a knob for opening and a knob for opening the drain hole, a base material and a surface sheet covering the base material are laminated via an adhesive layer,
A separation region in which a release material is applied between the base material and the topsheet, a non-release region disposed in the release region, and another non-release region disposed adjacent to the release region. ,
In the non-peeling area in the peeling area, a half cut for forming a drain hole opening is formed in a range from the base material on the inner surface side to the adhesive layer, and a boundary is formed between the peeling area and the adjacent non-peeling area. A half cut for release is formed on the top sheet linearly along the line, and the knob for opening the drain hole is gripped, and the top sheet is peeled from the substrate surface to form a half cut for forming the drain port opening. There is described a lid material capable of forming a drain opening by cutting it out. However, in the lid material having this configuration, since the half cut for forming the drain hole opening is formed in the non-peeling area in the peeling area, the non-peeling area is formed in the peeling area and the non-peeling area is formed. Since the half cut for forming the drain opening is formed in the separation area, it is necessary to accurately form the non-separated area and register the non-separated area with the half cut for forming the drain opening, which complicates the manufacturing process. Disadvantage.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a lid material having a hot water hole, which can be easily formed with a hot water hole, has a simple manufacturing method, and is excellent in sealing performance.

[0005]

The outer lid and the inner lid have a shape provided with an opening knob and a knob for forming a hot water drain hole protruding outward at positions opposed to the outer peripheral edge. The lid material is formed by laminating with an adhesive resin layer, and is used by being attached to the opening portion of the container by a lid material heat bonding portion, and the outer lid has outer peripheral edges on both sides of a hot water hole forming knob. An outer lid cut line to be connected is formed, and a region surrounded by the hot water hole forming knob and the outer lid cut line is a hot water hole forming region, and the peeling means is formed so as to face at least the hot water hole forming region. In the hot water hole forming area, a hot water hole cut penetrating the inner lid and the adhesive resin layer is formed, and the inner lid and the adhesive resin layer are applied to the inside of the hot water hole forming knob so as to cover the heat bonding portion of the lid material. With a configuration in which a cut line for forming a hot water hole is formed, the lid material By grasping the knob for forming the hot water hole of the package attached to the opening of the package and peeling off the lid material, it faces the hot water hole forming area surrounded by the cut line for forming the hot water hole and the cut line for the outer lid. The outer lid to be removed can be partially peeled off and cut off at the outer lid cut line, so that a hot water hole can be easily formed and the hot water can be drained. Further, since the lid member is thermally bonded to the opening of the container and sealed, the odor of the contents does not leak out of the package.

[0006] In the lid material with a hot water hole, the outer lid is made of a paper layer, the peeling means is made of a release layer formed on the entire inner surface of the paper layer, and the release layer is made of kaolin, calcium carbonate,
Latex, consisting of a casein-based composition,
When the adhesive strength between the paper layer and the release layer is 50 to 150 g / 15 mm in width, the paper layer and the release layer can be easily separated from each other. Can be formed. Further, since the paper coat layer formed on the paper layer can be used as the release layer, the production process can be simplified and the production of the lid material is facilitated.

[0007] In the above lid material having a hot water hole, the peeling means is constituted by a release layer partially formed so as to face the hot water hole forming region on the inner surface of the outer lid. Regardless of the type of the constituent material, it is possible to peel off between the release layer and the adhesive resin layer, so that the outer lid can be peeled off and the drain hole can be easily formed.

[0008] In the above-mentioned lid material having a hot water hole, the cut line of the outer lid is linearly arranged so that the closed side of the U-shaped cut faces the knob side for forming the hot water hole. By peeling off the lid material by grasping the knob for forming the drain hole, the outer lid covering the drain hole forming area is peeled off, and the outer lid can be easily cut along the outer lid cut line. The formation of a drain hole becomes extremely easy.
